Draining Lake Powell to fill Lake Mead

Should we drain Lake Powell to make sure we can save Lake Mead? It's a proposal being made by some scientists in the Colorado River watershed, who say it's more important that Lake Mead stay above a certain level than Lake Powell. The U.S. Bureau of Land Management isn't quite on board with the idea; they're working on some short-term solutions right now to help Lake Powell. Do you agree with the idea? Holly and Greg are split. They go through the pros and cons of this proposal.
